A jet bath designed to use minimum water, to use a formed in place low cost waterfall type water inlet, to have pulsating and massaging air-water jets appropriately located in the tub, to allow user adjustment of water temperature, to prevent heating the water above 122 degrees Fahrenheit and prevent tripping of a manually resettable high temperature limit switch with initial filling of the tub with overheated water.

[ What is claimed is:] [1.] A rapid-fill vacuum formable jet bath comprising:a) a tub; said tub having arm rests and a partially raised bottom to form a shape to fit a body in a reclining position with knees raised and to minimize water usage and filling time;b) a waterfall type water inlet means with said waterfall type water inlet means being integrally formed in a wall of said tub by forming a chamber in said tub, connecting a hot and cold water valve to said chamber and cutting a slot type opening in said chamber, said waterfall type water inlet means acting to mix hot and cold water and to discharge a mixture of said hot and cold water through said slot type opening in said waterfall type water inlet means thereby forming a sheet of effluent water;c) a multiplicity of aspirator type air-water jets in said tub;d) a water circuit and a circulating water pump; said circulating water pump circulating water in said water circuit from said tub to a water inlet connection in each of said aspirator type air-water jets;e) an adjustable regulating thermostat with a first water temperature sensor therein, and a second water temperature sensor operatingly installed in said water circuit;f) an air header means with an adjustable air inlet to provide air to each of said multiplicity of aspirator type air-water jets;g) an electrical heater means contained in a T shaped unit and operatively connected in said water circuit to heat water exiting said circulating water pump;h) a control means in said T shaped unit to adjustably control current to said heater means to regulate temperature of said circulating water and to prevent overheating of said water; said control means providing redundant controls to prevent overheating of said water and consisting of:1) an electrical circuit having said electrical heater means in said electrical circuit and a water pressure-to-close electrical switch operatively connected to said water circuit to allow current flow to said heater means in said electrical circuit when said water pressure-to-close electrical switch is held in a closed position from pressure in said water circuit;2) a manually resettable high temperature limit switch means operatively connected in said electrical circuit, said manually resettable high temperature limit switch means further comprising a thermistor means wherein current flow to said thermistor means opens said manually resettable high temperature limit switch means thereby interrupting flow of current to said heater means;3) said adjustable thermostat with said first water temperature sensor therein operably connected with a thermostat switch in said electrical circuit to allow current flow to said heater means to maintain a water temperature chosen by user adjustment of said adjustable thermostat; said thermostat switch being in series with said manually resettable high temperature limit switch means;4) an automatic high temperature limit switch operatively connected with said second water temperature sensor with said second water temperature sensor operating to close said automatic high temperature limit switch at about 122 degrees Fahrenheit; said closing of said automatic high temperature limit switch allowing a current flow to said thermistor means which is operatively connected with said manually resettable high temperature limit switch means causing said manually resettable high temperature limit switch to open to interrupt said current flow to said heater means.
